Abstract

L'INVENTION CONCERNE UN TRANSDUCTEUR DE FORCE A QUARTZ. LE TRANSDUCTEUR 10 COMPREND DEUX PARTIES TERMINALES 12 NON VIBRANTES QUI TRANSMETTENT DES FORCES DE FACON EGALE A DES PARTIES BARRES 14 INTERMEDIAIRES RELIEES ENTRE ELLES. CES PARTIES BARRES SONT SOLIDAIRES DES PARTIES TERMINALES ET SEPAREES L'UNE DE L'AUTRE PAR UNE FENTE 16. LE CRISTAL DE QUARTZ EST UN CRISTAL PIEZO-ELECTRIQUE RECTANGULAIRE MINCE D'EPAISSEUR T, DE LONGUEUR L ENVIRON EGALE A 100T, DE LARGEUR W ENVIRON EGALE A 10T, LA FENTE AYANT UNE LONGUEUR L D'ENVIRON 0,6L ET UNE LARGEUR W QUI N'EST PAS SUPERIEURE A T, LES PARTIES TERMINALES AYANT UNE LONGUEUR L ENVIRON EGALE A 2W, ET CHACUNE DES PARTIES BARRES AYANT UNE LONGUEUR L A PEU PRES EGALE A L ET UNE LARGEUR W SUPERIEURE A 2,5T. UN MOYEN 18 PORTE PAR LES PARTIES BARRES SERT A FAIRE ENTRER CELLES-CI EN VIBRATION A DES FREQUENCES PROPORTIONNELLES AUX FORCES APPLIQUEES AUX PARTIES TERMINALES. LE RESONATEUR DE L'INVENTION PRESENTE UN FACTEUR DE QUALITE MECANIQUE Q TRES ELEVE, PAR EXEMPLE D'ENVIRON 100000.THE INVENTION RELATES TO A QUARTZ FORCE TRANSDUCER. THE TRANSDUCER 10 INCLUDES TWO NON-VIBRATING TERMINAL PARTS 12 WHICH TRANSMIT FORCES EQUALLY TO INTERMEDIATE BAR PARTS 14 LINKED TO ONE Another. THESE BAR PARTS ARE ONE OF THE TERMINAL PARTS AND ARE SEPARATED FROM ONE ANOTHER BY A SLOT 16. THE QUARTZ CRYSTAL IS A THIN RECTANGULAR PIEZO-ELECTRIC CRYSTAL OF THICKNESS T, OF LENGTH OF ABOUT 100T, OF WIDTH W ABOUT 10T, THE SLOT HAS A LENGTH L OF ABOUT 0.6L AND A WIDTH W WHICH IS NOT GREATER THAN T, THE TERMINAL PARTS HAVING A LENGTH L ABOUT EQUAL TO 2W, AND EACH OF THE BAR PARTS HAS A LENGTH A LITTLE NEAR EQUAL TO AL AND A WIDTH WIDTH GREATER THAN 2.5T. A MEANS 18 CARRIED BY THE BAR PARTS IS USED TO MAKE THEM ENTER INTO VIBRATION AT FREQUENCIES PROPORTIONAL TO THE FORCES APPLIED TO THE TERMINAL PARTS. THE RESONATOR OF THE INVENTION HAS A VERY HIGH MECHANICAL QUALITY FACTOR Q, FOR EXAMPLE OF ABOUT 100,000.
